How To Make a Catapult Shooting Game with Cocos2D and Box2D
Today as my AltDevBlogADay post I'll just leave you with a link for my first tutorial as part of Ray Wenderlich's team. It was a wonderful learning experience, not only of Cocos2d but also on writing tutorials.
I think it was a good idea to use GitHub to share the tutorial files.
Check it out and let me know what you think.
